认识油田开发规律 科学合理开发油田

Understanding oilfield development rule,scientifically and reasonably developing oilfields

系统总结了油田开发中具有普遍性和实用性的两项渗流规律、流体流量变化规律、厚油层水淹规律、孔隙结构特征规律、油层压力变化规律、产量变化规律、油层工作方式和井筒工作方式规律、井网与开发效果关系规律、剩余油分布规律、油层与注入剂配伍性规律及描述这些基本规律的方法。给出了油田开发阶段划分的 3种方法 ,提出了油田开发不同阶段应采取的调整措施 ,为提高油田开发效果奠定了基础。油田开发要经历不断认识的开发历程 ,先易后难的开发程序 ,分而治之的开发方法 ,物质平衡的驱动方式以及逐步强化的开采手段。

There are some universal and applicable rules in oilfield development.Two phase seepage rule, flow rate changing rule of fluids,watered-out rule of thick oil-bearing reservoirs,characteristics of pore structures,reservoir pressure changing rule,oil production changing rule,working mode of oil reservoirs,working mode of well bores,relationships between well pattern vs development effects,distribution rule of residual oil and compatibility rule of reservoir vs injectants is systematically summarized in this paper. And the methods describing these basic rules are introduced. Three methods divided the oilfield development period are discussed and adjustment measures adopted at different development period are put forward. The purpose of this paper is to improve the development effects. Development process should be understood continuously. Development procedure should be from easy to difficult and development methods should be divided and managed,type of driving should be material balance method and production scheme should be intensified step by step.
